Synthesis of interference filters for the UV spectral region

Resumo

Methods for manufacturing interference band-pass filters for the ultraviolet spectral region are described. These filters have a high transmittance and a high contrast in the working spectral region, while their transmittance in the region of “background” signals is low. The original design of a hybrid filter, whose operating principle is based on the multiple reflections of light rays, is considered. The experimentally measured spectral characteristics of filter specimens are presented.
